Thanks for the reply nando, I'll try that out (once I have the money). What is your thought about this?

Should I buy a PE4C 2.1 or 3.0? Realistically, does the 3.0 with 5 gbps mPCIe/ EC outperform the 2.1 with mPCIe + EC setup, or even the 2.1 with one mPCIe/ EC setup?

How many mPCIe slots does the 2570p have and is it true that mPCIe gives better performance than EC? Do I need to perform a DSDT override and/or even a setup 1.30 if I use mPCIe link with the hp 2570p instead of EC link?

Yeah of course i5 laptop will suck but I'm more shocked about how much powerful a desktop processor is compare to a laptop processor. A 5660 points difference, that's a lot more than what I thought it could be. On the other hand, I'm glad that graphics point isn't suffering much.

I currently have a hp 2570p, a gigabyte gtx 670 and a 650w ATX PSU.

Thanks in advance.

ps: I benchmark my above hardwares with the EXP GDC V6 with 3Dmark11 and the result is this

Compare to this

-1287 in graphics point and -5660 physics point!

Is it because games with physx suffer huge drop in fps when using eGPU or my setup or my CPU (or both) just suck?

Depends what GPU you have. a GTX 670 needs 500 watts of power as a minimium, most likely you need a PSU to power the GPU. Also, what do you get with the iGPU (integrated GPU) as it could just be because you did not do it correctly and the GPU is not being used for the program/game.

I personally think its your CPU bottlenecking the connection as if it was because of the Expresscard slot, the fps would change depending on the settings, but since you said they were the same no matter what setting they are on I am lead to believe that it is your CPU as the CPUs load does not change depending on the setting, just the game itself.

Though, you might want to wait for Nandos response as i'm stating things as I see them(and I haven't even done a egpu yet (waiting for Thunderbolt 3 laptops to be released).

On a different note, Nando, if a laptop have a dedicated GPU (with Optimus/switchable) is it guaranteed to be able to run an eGPU. Also, will a Thunderbolt 3 laptop be much easier to setup.

Thanks for the reply, I'm currently buying a 650w PSU to see if there's any differences. Though I would prefer that I don't need a 650w, would a 400w works? I just use the PSU to power up the 670 and the 670 alone so the PSU should be able to direct its power to the 670? Does it work that way?

In the case of my CPU actually rendered my game instead of my GPU like you said then how can I fix it that problem?

I've a hp 2570p + EXP GDC V6 Express Card + Gigabyte GTX 670 windows 8.1 UEFI setup. It seem like my express card can't handle the GTX 670 capability because when I play Metal Gear Rising for benchmarking, no matter how low I decreased the setting, the fps is still the same as the highest setting leading me to the conclusion that the express card simply can't transfer all of the data between the 670 and my 2570p fast enough. Is there a solution for this? I've switched my Express Card setting from Gen 1 and Gen 2 before the test.

ps: I forgot to mention, my fps is about like, below 10?

ps2: I guess I figure it out after watching a few videos about egpu. My setup doesn't have a PSU, is this the source of the problem? What kind of PSU do I need? Is a 650w necessary or not?

What is the purpose of the switch on the V6?

If I've a V6, am I done for? Can it power a GTX 670?

Can I use the HDMI - Expresscard Cable to connect my PS3 to my PC laptop screen?

Thanks.

I have question about this, does enable ASPMs in the ACPI FACP and set L0s L1s in the pci-e configuration cause problem for the eGPU in windows 8.1? Another question: I've a EXP GDC V6, can it power a GTX 670 with no problem?
